Burkhard Büdel et al.
Biological soil crusts (BSCs) are found in all dryland regions of the world, including the polar regions. They are also known to occur in the southern African region. Although there were a number of case studies on BSCs from that region, we...

Shah Md Asraful Islam et al.
We examined the biodiversity of bacteria associated with oyster-shell waste during a 1-year storage period using 16S ribosomal DNA analysis. Temperature variation and structural changes of oyster shell were observed during storage. Initial ...

Anthropogenic nitrogen (N) deposition affects a wide range of soil processes including phenol oxidase (PO) activity and soil organic matter dynamics. Depression of phenol oxidase activity in response to N saturation is believed to be mediat...
Potential effect of freshwater virus on the structure and activity of bacterial communities in the Marennes-Oléron Bay (France) [0.03%]
J C Auguet,H Montanié,H J Hartmann et al.
J C Auguet et al.
Batch culture experiments using viral enrichment were conducted to test the response of a coastal bacterial community to autochthonous (i.e., co-existing) or allochthonous riverine viruses. The effects of viral infections on bacterial dynam...

The effect of copper on the structure of the ammonia-oxidizing microbial community in an activated sludge wastewater treatment plant [0.03%]
Pamela Principi,Federica Villa,Barbara Giussani et al.
Pamela Principi et al.
Molecular approaches based on both whole-cell and extracted DNA were applied to assess chronic and acute effects of copper on the ammonia oxidizing bacteria (AOB) community in an activated sludge system. The ammonia monooxygenase amoA gene ...
Importance of viral lysis and dissolved DNA for bacterioplankton activity in a P-limited estuary, Northern Baltic Sea [0.03%]
Lasse Riemann,Karin Holmfeldt,Josefin Titelman
Lasse Riemann
Through lysis of bacterioplankton cells, viruses mediate an important, but poorly understood, pathway of carbon and nutrients from the particulate to the dissolved form. Via this activity, nutrient-rich cell lysates may become available to ...

In pelagic ecosystems, the principal source of organic matter is via autotrophic production and the primary sink is through heterotrophic respiration. One would therefore anticipate that there is some degree of linkage between these two com...
Hydrological control of organic carbon support for bacterial growth in boreal headwater streams [0.03%]
Martin Berggren,Hjalmar Laudon,Mats Jansson
Martin Berggren
Terrestrial organic carbon is exported to freshwater systems where it serves as substrate for bacterial growth. Temporal variations in the terrigenous organic carbon support for aquatic bacteria are not well understood. In this paper, we de...
Multi-site analysis reveals widespread antibiotic resistance in the marine pathogen Vibrio vulnificus [0.03%]
Craig Baker-Austin,J V McArthur,Angela H Lindell et al.
Craig Baker-Austin et al.
Vibrio vulnificus is a serious opportunistic human pathogen commonly found in subtropical coastal waters, and is the leading cause of seafood-borne mortality in the USA. This taxon does not sustain prolonged presence in clinical or agricult...
